The College had a continuing and quite serious run of thefts from the library and general College environs during the four years I worked at there. To be fair, the level of theft was probably on par for a non-theological location, but it was so much more noticeable given that the thefts occurred in a place where 'thou shalt not steal' is a basic tenet.

Which simply reinforces the notion that saying that you are a Christian means absolutely nothing. It's your actions that show what you are. However, this also means that using the Bible as a thief repellent is not only ineffectual, but simply stupid.
